Explanation:
Mass culture is a set of cultural objects, goods or services, produced by cultural industries, which are aimed at a diverse audience.
According to critics, such as Adorno, the mass follows the same thing. According to the Frankfurt School, mass culture is the main means through which capital would have achieved its greatest success. Then, the whole system of mass production of goods, services and ideas would have accepted, in general terms, the model imposed by the capitalist system by the hand of consumerism, technology and rapid satisfaction. This culture is defined through the mass media from the nineteenth century (printing, radio, cinema, television, and even today with the Internet). From this appear the mass societies that are shaped by a society of individuals aligned to capitalism, where the bourgeoisie has the power to introduce products, ideologies, etc. into society. and thus curtail the freedom of expression of a fully capitalized society.
It is considered as the development of a new model in which differences and inequalities are reinforced with increasingly developed marketing strategies and instruments. Science and knowledge are put at the service of the production of stereotyped values and symbols.
The three fundamental pillars of this culture are: a commercial culture, a consumer society and an advertising institution
 
        
             
        
        
        
In multicellular organisms individual cells grow and then divide via a process called mitosis, thereby allowing the organism to grow. Cellular division and differentiation produce and maintain a complex organism, composed of systems of tissues and organs that work together to meet the needs of the whole organism.
        
             
        
        
        
Answer:
The correct answer is option C (voltage gated Na+ channels).
Explanation:
Output region or axon terminal is the structure of neuron which transmits the signals to other nerve cells.
The signal is transferred via action potential generated by the dendrite cell which moves along the axon and reaches the synaptic junction.  
At the synaptic junction, voltage-gated channel (Na+) channels located in the membrane of the axon terminal cell opens due to the changes in the electric membrane potential which play important role in returning the depolarized cell to a resting state.
Thus, option C (voltage-gated Na+ channels) is the correct answer.
